javascript - knockoutjs javascript 到 CoffeeScript

Question

如何将这个 javascript 转换为 Coffeescript？

$(function() {
  function AppViewModel() {
    this.firstName = ko.observable();
  }

  ko.applyBindings(new AppViewModel());
});

我尝试过这个，但它破坏了 knockoutjs 绑定(bind)

jQuery ->
  AppViewModel = ->
    this.firstName = ko.observable("something")

  ko.applyBindings(new AppViewModel())

这是coffeescript 生成的内容

(function() {

  jQuery(function() {
    var ViewModel;
    ViewModel = function() {
      return this.firstName = ko.observable();
    };
    return ko.applyBindings(new ViewModel());
  });

}).call(this);

Answer 1

这成功了。但我认为真正的解决方案是——学习knockoutjs时不要使用coffeescript

jQuery ->
  class AppViewModel
    firstName : ko.observable()

  ko.applyBindings(new AppViewModel)
